Certain aspects direct to basic input/output system (BIOS) failover update with a service processor (SP). In certain embodiments, the system includes a host computer and a SP. A CPU of the host computer loads and executes a current BIOS image stored in a BIOS chip to a memory as a BIOS instance. The SP receives, from the executed BIOS instance at the host computer, a BIOS image as a failover backup image, and stores the failover backup image in the volatile memory of the SP. When an error occurs at the host computer, the executed BIOS instance sends a request for the failover backup image to the SP. In response, the SP sends a copy of the failover backup image to the host computer such that the executed BIOS instance may replace the current BIOS image stored in the BIOS chip with the copy of the failover backup image. |

1. A system, comprising:
a host computer, comprising a central processing unit (CPU), a memory and a basic input/output system (BIOS) chip storing a current BIOS image, wherein the CPU is configured to load a copy of the current BIOS image to the memory and execute the current BIOS image as a BIOS; and a service processor (SP) connected to the host computer via a system interface, the SP comprising a processor, a non-volatile memory, a volatile memory and a system interface, wherein the non-volatile memory stores computer executable codes configured to, when executed at the processor,
receive, from the BIOS being executed at the CPU of the host computer through the system interface, a BIOS image as a failover backup image, and store the failover backup image in the volatile memory;receive, from the BIOS being executed at the CPU of the host computer, through the system interface, a request for the failover backup image; andin response to the request for the failover backup image, send a copy of the failover backup image to the host computer through the system interface such that the BIOS being executed at the CPU of the host computer replaces the current BIOS image stored in the BIOS chip with the copy of the failover backup image; wherein the BIOS is configured to, when executed at the CPU,
retrieve a copy of the current BIOS image from the BIOS chip, and send the copy of the current BIOS image as the failover backup image to the SP through the system interface;generate the request for the failover backup image, and send the request for the BIOS image to the SP via the system interface;receive the copy of the failover backup image from the SP via the system interface, and stores the copy of the BIOS image in the memory; andreplace the current BIOS image stored in the BIOS chip with the copy of the failover backup image stored in the memory. |
